The CM3196 is a sinking and sourcing regulator specifically designed for DDR-I, -II VTT bus termination. The output voltage accurately tracks VDDQ/2. For DDR-I it can source and sink current up to 2A with a load regulation of 0.5%. This current adequately serves both single and dual channel DDR-I memory systems. For power conscious notebook applications, the CM3196 also operates from a VDDQ of 1.5V or 1.8V with less current drive. For DDR-II applications, the CM3196 provides up to 0.6A at 0.9V to drive the memory controller VTT.
